finding a value from an array, returning the name at the header of that column.

[Kirk Brown]

example:

h i j k l
40 2 3 4 5 6
42 3 4 6 7 8
44 4 5 6 7 8



from column 1: =44
from row defined by 44, find the letter name associated with the value=6
what letter is associated with this column.

If A1 is empty, B1:G1 hold h, i, j, k, l and the rest of the data is in A2:G4

you could use the formula

=INDEX(INDEX($A1:$G4,1,0), 1, MATCH(6,INDEX($A$1:$G$4,0,MATCH(44,INDEX($A$1:$G$4,0,1),0)),0))

This is more complicated that stricktly is needed so that $A$1:$G$4 can be replaced with a named range if you are using them.

I came up with

=INDEX(B1:F1,1,MATCH(A8,OFFSET(B2,(MATCH(A7,A2:A4))-1,0,1,5)))

assuming the same cell references as Mike.
This returns j using your sample data.

After testing, I see that I swapped rows and columns at one point.
This is another version, using the named range dataRange (=$A$1:$G$4)

=INDEX(dataRange,1,MATCH(6,INDEX(dataRange,MATCH(44,INDEX(dataRange,0,1)),0)))

Gerald's formula is easier to understand and edit.

example:

h i j k l
40 2 3 4 5 6
42 3 4 6 7 8
44 4 5 6 7 8



from column 1: =44
from row defined by 44, find the letter name associated with the value=6
what letter is associated with this column.
